The Fort Worth Press - Stocks rise, oil down as traders weigh Iran sanctions threat

Treasury Secretary Scott Bessent said the White House was declaring an "economic D-Day" against Iran and threatened to hit countries that trade with it.

The threat comes as talks to reopen the Strait of Hormuz remain stalled, with neither side showing any sign of backing down.

That had pushed oil prices up for most of August, fuelling inflation fears and pressuring bond markets.

The US said expanded "secondary" sanctions would target Iran's digital assets, technology, gold, aviation and shipping sectors, but gave no timeline and named no specific countries beyond Iran.

Analysts said the measures were softer than expected.

"European stock markets rebounded early Tuesday with some relief evident from the lack of any material increase in the economic pressure on Iran," said Neil Wilson, investor strategist at Saxo UK.

Oil prices fell around three percent, with the international benchmark Brent back below $90 a barrel.

In Europe, London, Paris and Frankfurt rose, with German data showing the country's second-quarter growth was stronger than previously estimated.

Attention is also focussed on Nvidia's earnings release on Wednesday, which have become a key test of the AI boom as concerns grow over whether the sector can match lofty expectations.

"The most actively traded stocks in the US right now are all the major AI names... this adds to evidence that Nvidia's results will be a key driver of price action, and potential volatility later this week," said Kathleen Brooks, research director at XTB trading group.

In Asia, tech-heavy Seoul rose, along with Tokyo and Shanghai, while the Hong Kong market was flat.

Investors are also looking to the annual Jackson Hole gathering of central bankers, economists and finance chiefs beginning Thursday, where Federal Reserve boss Kevin Warsh is due to speak.

His comments will be parsed for clues about monetary policy, with inflation still stubbornly high and after Bessent said the Treasury would buy back more of its own bonds to push down borrowing costs after the 30-year yield hit a 19-year high.

The move has weighed on the dollar and helped lift bitcoin above $80,000 for the first time since May, with the prospect of crypto-friendly US legislation also providing support.

The Canadian dollar edged slightly lower against the US dollar after US President Donald Trump vowed to double tariffs on Canadian vehicles, fanning a trade war.

Trump's threat comes after the neighbours failed to reach a deal to avert new 50 percent US tariffs on select Canadian goods. Canada will announce Tuesday its response to the new levies.
